What probiotic is worth recommending?

There is no single answer to this question. A lot depends on what you expect from a probiotic. Other strains are used, for example, in gastrology, and others in gynecology. There are also psychobiotics used to treat depression and other psychological disorders. If you write for what purpose you want to use a probiotic, I may be able to give a more specific answer. At this point, the question is too general. However, there are a few key elements when choosing a probiotic: 1. It is worth choosing a preparation with the status of a drug, because the manufacturer guarantees a specific, minimum amount of live bacteria in the product until the end of the expiration date (this is a PRICELESS FEATURE!) 2. All strains are precisely defined – we have given specific names and strain designations, e.g.: Lactobacillus rhamnosus R0011 3. Low temperature is a factor that prolongs the survival of bacteria. All drugs containing probiotic bacteria – must be stored in the refrigerator. 4. The fresher the probiotic, the better. It is not worth being tempted by the sale of supplements with a short expiration date. The older the preparation, the less stable bacterial cultures it has.
